Obverse: At the top edge, the words "WASSER" (water) and "ENERGIE" (power/energy) are written in capitals, followed by the French and Italian designations "eau" and "acqua"; just below that, turbine components and data on water consumption in Switzerland are depicted. The lower half of the image shows an abstract colour image of water and water flows. In the dark, the fluorescent elements printed on the coin begin to glow.

Reverse: Parallel to the edge the legend "CONFOEDERATIO HELVETICA 2021" step-like displaced in two lines; above of the centre the Swiss cross and at the bottom in three lines "20 / B / FR".

Hydropower is one of the oldest energy sources in the world and was already used more than 5,000 years ago. It offers an efficient, climate- and environmentally friendly form of electricity generation. A total of 677 plants are in operation throughout the country, producing an average of around 36,741 gigawatt hours of electricity per year and thereby supplying 56% of Switzerland's power needs.

This fine coin is not only captivating with its colourful details, it also reveals another secret in the dark: the fluorescent elements printed on the coin begin to glow, which is another highlight in the history of Swiss coins.
